# Alentejo wine production and sustainability developments > Live situation record from CLSTR: https://clstr.news/situations/alentejo-wine-production-and-sustainability-developments > Updated: 2026-09-27T21:02:53.000Z. Sources: 6. Developments: 2. The Alentejo wine region in Portugal is undergoing regulatory and operational shifts focused on production standards and sustainability. Initially, the Institute of Vine and Wine introduced new specifications for Alentejo Denomination of Origin (DO) and Alentejo Geographical Indication (IG) wines. These regulations updated altitude references for the Portalegre sub-region, established new labeling criteria for ‘vinhas velhas’ (old vines) and ‘vinhas velhas centenárias’ (centenary old vines), and set specific yield limits. The updates also formalized the ‘vinho de talha’ designation for wines produced in traditional clay amphorae under strict fermentation and bottling requirements. Following these regulatory updates, the industry has seen an expansion in sustainability efforts. The Comissão Vitivinícola Regional Alentejana (CVRA) reported that over 35% of the region's production has achieved sustainable certification through its Sustainability Program for Alentejo Wines (PSVA), covering more than 5,750 hectares. Additionally, major producers like Sogrape are implementing long-term sustainability programs and investing in meteorological technology to enhance vineyard resilience against climate change. ## Timeline ### 2026-09-27: Portuguese wine industry expands sustainable production and certification Sustainability efforts are growing in the Portuguese wine industry, with over 35% of Alentejo's production now certified sustainable and Sogrape expanding its long-term environmental and technological programs. 5 sources. https://clstr.news/cluster/portuguese-wine-industry-expands-sustainable-production-and-certification ### 2026-08-31: Alentejo wine production faces new regulatory specifications New regulations for Alentejo DO and IG wines introduce specific labeling rules for old vines and traditional ‘vinho de talha’ production, while removing altitude limits for Portalegre. 2 sources. https://clstr.news/cluster/alentejo-wine-production-faces-new-regulatory-specifications --- Cite as: Alentejo wine production and sustainability developments.
